Abstract

An improvement in the float process for the manufacture of glass ribbon having a thickness different from the equilibrium thickness, said improvement being characterized in that jets of molten metal are impinged against both side edge portions of the glass ribbon from nozzles disposed below the glass ribbon and in the molten metal bath, and a lateral stretching force, in the case of outward impinging, or a lateral contracting force, in the case of inward impinging, is imparted to the glass ribbon by the momentum of the molten metal impinged from the nozzles against the glass ribbon.
